Anti-Fraude SMS - Testing Program

What is the Anti-Fraude SMS app?

This Android application analyses received messages and alerts users whenever it detects potential fraud or scam attempts. Its major advantage is that everything happens locally on the device, ensuring full privacy: no messages containing private data are sent to external servers.

The app works silently in the background, remaining in watch mode. It works fully automatically: as soon as an SMS arrives, the analysis is performed. If the message is considered suspicious, a potential fraud, or a fraud already confirmed by the community, the alert immediately appears on screen.

Alert Types

SMS message analysis can return 5 classification types and 4 alert types.

The strength of the Community (Crowdsourcing)

Whenever the app shows an alert, the user can vote to classify the message as Safe, Spam, or Fraud. These votes are what make it possible to confirm whether a message is, in fact, a known threat.

Once a message reaches a certain volume of votes, it is automatically marked as Fraud (confirmed). From that moment on, anyone who receives a similar message will immediately see the Fraud (confirmed) warning.

To access these classification options, simply enable advanced mode in: Settings -> Advanced Mode.

Offline mode

The app was designed to work without depending on internet or mobile data.

However, there is one small detail: immediate Fraud (confirmed) classification depends on a file that is downloaded once a day. Without a connection, the app continues to analyse messages, but they will be shown as Potential Fraud.

In addition, while the phone is offline, votes are not sent to the server and remain waiting for a connection before being counted.
